Ayurveda gives guidelines/tips for the right diet, right lifestyle and herbal remedies for healthy eyes. The basic principle of Ayurveda is based on tridosha/elements (vata, pitta and kapha) which is responsible for normal functions of the body and when vitiated leads to disease. The role of doshas is different from organ to organ, so etiological factors for vitiation of doshas are also different for different organs. In the eye, Alochaka Pitta(a type of pitta) is considered responsible for visual perception. The factors which vitiate pitta will lead to eye diseases.
